Has same problem a couple of times. Took out the light box and cleaned it. Note: there is a small screen in the back of the light box that clogs fast. Also had to unplug tv a few times to reset the error message. Also had same problem that ended up being heat from the stereo receiver that was located in the stand directly below the tv. This tv is very tempature sensitive. If your tv stand is warm, remove the heat source.

In the 65" TVS there are 4 or more fans One of these is not functioning Probably the one over the power supply itself This will cause it to heat very quickly and shut down in a matter of about 20 seconds.

only way to find out which fan is not working isw to remove the back.

52' DLP Mitsubishi HD T.V. gets an error message on the bottom of the screen ''T.V. will shut down. Check that air flow is not blocked'' T.V. is in the open and air flow is not blocked. There is also a...


most rear projectors will turn themselves off whenever the lamp is dead. what we call protective mode. in this case the yellow light may be for the lamp. otherwise check if all the fan are working properly.
But MAKE SURE you let sufficient time for the tv to cool off before unplugging the main.

hope this helps

How do I test the Lamp Thermal sensor?


Good Day;

The indication that the sensor is bad is showing the "air flow message", not an item that can be tested with positive results. Replace, it's only a couple of dollars. Good Luck, big IRISH.

Air flow blockage


Take care of it NOW. We ignored the error (knowing we're under a service plan so we'd get to it eventually). Then last week the TV just cut out and we got no picture and the red lamp light came on. Service guy came out today and replaced the lamp and it didn't work and then called Mitsubishi. They said it is probably a very common capacitor problem on the power supply board. If you open the back and take a look you are likely to see bulging caps. Parts C9A37 and C9A38. The caps are cheap if you can find them, but the parts are really hard to find right now so Best Buy is actually replacing these for people under service plans rather than fixing them. The message you are getting is a sign that the caps are getting too hot and need to shut down to cool off... It will eventually ruin your lamp if you let it go on.

Good luck! BTW, our guy said the repair will run you about $200 if you can't do it yourself, but someone else on this board with guru status recommends a kit that comes with a CD and a manual that will help you fix this. They even give a web address to order it. If we weren't under a service plan I would be going this route...

have you cleaned the air filter located on the side of the set? If that doesnt work the thermal sensor will need replacing.

Tv Shuts off occasionally 1min upon power up shows red lamp light


Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.


Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

Air flow error


There is a Mitsubishi service bulletin for this problem.The source of the problem is the connector to the thermal fuse by the lamp. The fix is to cut the connectors off and hard wire the fuse (you will have to splice in a 3"inch wire extension to make it reach once the 2-wire connector is cut off)

Error Message


. Set shuts off after displaying the message "TV will shut down in a few seconds. Please check if the air flow is blocked." After shutdown, it may have a yellow status LED, self diagnostics indicates error code 38. To repair, replace the Lamp Thermal Sensor with the new version, part # 299P313010A. The sensor is located on the Lamp Cartridge Housing. See Service Tip VS-72B. Under rare circumstances, when a replacement thermal sensor is not available, refer to the original Service Tip, VS-72 (page 2 and 3 of VS-72B) If error 3-4 then this maybe problem:. Check to see if the lamp is on when the unit is off (in standby) if it is components on the Power PWB... K9A20 and/or K9A21 are shorted. Also, R9A02 may be open. Possible side effects ... deformed lamp exhaust duct and damaged lamp. Replace PWB-POWER part # 934C228003 and if necessary, Lamp part # 915P049010, Lamp Exhaust Duct part # 642B155010, and/or Lamp Exhaust Duct Cover part # 642B156010. See Service Tip VS-73 2. If the lamp never lights suspect the Lamp part # 915P049010
